l claim as my invention:

l. The method of forming sub-aqueous concrete structures which consists in molding a section of said structure above the surface of the water, lowering said section into the water but leaving the top of the section above the water, molding another section on top of the first section, and so on SUCCPSSIVG-l) upon the lust one and upon one another, and

until the bottom section rests upon the ground.

2. A process of sub-aqueous construction which consists in molding 11, section of plastic material at the surface ot the water, lowering I do not wish to he limitedto such l l l i l the bottom of the mold and the section thereon, then molding a second section upon the first and so on suceessively until the hottom of thestructure rests upon the ground or bottom foundation.

3. A process of dock construction which consists in molding and reinforcing a section of plastic material at tho-surface ofthe the grouml or hottoni foundation.

rial at the surface of the water, louering the bottom of the mold and thesection thereon, t

then molding a series of sections sueeessively bonding them together during the molding operation, and lowering all of the sections, as each'one is molded, until the bottom one rests upon the ground.

In witness whereof. I have hereunto set my hand this 21st day of March 1907.
